CARTRIDGE-CASE EXTRACTOR.

Specification of Letters Patent.

Patented Nov. 14, 1905.

Application filed December 12, 1904. Serial No. 236,633.

To all whom it may concern:

Beitknown that we, LAURENoE V. BENET, a citizen of the United States, and HENRLA.

lVIERGIE, a citizen of France, residing at Paris,

especially to extractors of the type which move longitudinally with the breech-block parallel to the axis of the gun, but are held against turning laterally while the breechblock is rotated from the locked to the unlocked position, or vice versa. The invention can also be applied to straight-pull breechblocks by suppressing the locking-arms on the breech-block. 'Extractors of this class are more especially adapted for use with guns of small caliber and especially where the action is rapid, and we have shown and described it as embodied in a gun of the general character of that described and shown in the patent to Benet and Merci, No. 696,306, granted March 25, 1902, and entitled Automatic In the drawings we have shown only so much of the gun and of the operating parts as is necessary to illustrate the action of the extractor, as the extractor mechanism only constitutes the subject-matter of our present invention.

Reference is had to the accompanying drawings, in which the same parts are indicated by the same letters throughout the several views.

Figure 1 shows the breech-block, partly in elevation and partly in section, with the motor-piston and the extractor mechanism in section and represents the position of the extractors when the breech-block is unlocked. Fig. 2 is a vertical half-section through the axis of the extractor mechanism, showing a portion of the gun, of the cartridge, and of the breech-block, and shows the position of one of the extractors just as the breech-block is being rotated for closing. Fig. 3 is a similar section and shows the position of one of the pair of extractors when the breech is closed and the extractors are engaged. The operation of the two extractors being identical, only one extractor is shown in Figs. 2 and 3. Fig. 4: is a plan view of the front end of the breech-block with the extractor mech= anism mounted thereon. Fig. 5 is a front elevation of the breech-block and extractor mechanism as seen from the left of Fig. 4. Fig. 6 is a similar view of the breech-block with the extractor holders or supports-and extractors omitted. Fig. 7 is a perspective view of the extractor holder with the extractors mounted therein as detached from the breech-block. Fig. 8 shows a section, on a reduced scale, of the breech-block on the line 8 8 of Fig. 4 and looking in the direction of the arrows and also shows the engagement of the extractor-holder and of the tenons of the breech-block with the housing at the breech of the gun. Fig. 9 shows a sectional elevation of the extractor holder or support, the lower half being shown in elevation with one extractor contained therein and the upper half being shown in section with the extractor removed; and Figs. 10 and 11 are details showing the extractor in perspective. Fig. 12 is a rear view of the casing at the rear of the gun with the mechanism removed and shows the longitudinal grooves for the extractor-holders.

A represents a part of the motor-piston, which may be gas-operated, as in the Bent and Merci patent aforesaid, and is provided with a sleeve A, in which is mounted the breech-block B, which breech-block is provided with cam-grooves B", into which projects a pin C, extending across the sleeve A, and this pin also serves to hold the firing-pin D, which, is mounted in the cavity D in the breech-block and projects rearward therein, as shown at cl. The point of the firing-pin (not shown) passes through the hole 7) in the front face of the breech-block. the engagement of this pin 0 with the camgrooves B after the gun has been fired the breech-block is caused to rotate from the locked to the unlocked position until the pin 0 reaches the position shown in Fig. 1. Then the breech-block is carried rearward the full length of the recoil of the motor-piston, and in returning to the initial position the breechblock is arrested by the breech or any other part of the gun-body, and the pin 0, cooperating with the cam-grooves B", causes the breech-block to rotate back to the locked position, as shown in Fig. 8. This action is described in detail in the Bent and Meroipatent aforesaid and constitutes no particular part of the present invention, and it will be obvious that a straight-pull breechblock By means of which does not rotate may be used with extractors of the character hereinafter described. The front end of the breech-block carries tenons B which are shouldered to the rear,

5 as at b to engage shoulders 70 on the housing K at the breech of the gun, as shown in Fig. 8, and as fully described in the Benet and Merci patent aforesaid, and these tenons are provided on their forward faces with cam-, grooves (shown most clearly in Flgs. 5 and 6,) which cam-grooves extend alongthe outer edge of the forward portion of the breechblock.

The extractors are supported in two blocks 5 E. connected together by or preferably made integral with a ring E which ring is mounted on the cylindrical portion B at the forward end of the breech-block. These blocks E are provided with lugs E, which engage the o shoulders t of the tenons B and the strain on the extractor in pulling out the empty cartridge-case is transferred to these lugsE. The extractors F, two in number, are oppositely disposed, so as to draw the cartridge- 5 case straight to the rear without binding against either side of the powder-chamber. The extractor-supports E slide longitudinally in grooves in the casing at the rear of the breech-block chamber, and thus the extractor- O holders and the extractors are held against 5 also shown in full lines in Fig. 5, the ring E with the blocks E may be readily drawn forward and removed from the breech-block, as in disassembling the parts.

The extractors are mounted to rock slightly 9 and to slide outwardly and inwardly in a recess E in the extractor-holders E and are each provided with a claw f, having an inclined face f adjacent thereto, with a shankf, traveling in an inclined groove 6* in the extractor-support,

5 and having a nose or lug f adapted to engage a shoulder 6 in the extractor-holder, as will be hereinafter described. Each extractor is also provided with a lever-arm f adapted to engage in the cam-groove b and with the stud f, to which the spring H is attached. This spring is mounted in a recess in the extractorholder, which recess is preferably enlarged somewhat in its inner end, as at e, to receive the end of the spring H, and thus this spring holds the extractor in its holder when the said holder is removed from the breech-block.

Grepresents the cartridge-case, (see Figs. 1, 2, and 3,) having the rim 9, and Krepresents a portion of the breech of the gun, having the inclined face Z0 registering with the extractor mechanism.

The operation of the device is as follows: Suppose the parts to be in the position shown in Fig. l and the motor-piston to be in its rearward position about to return on counterrecoil. The parts will remain in the position shown in Fig. 1 until the forward motion of the breech-block is arrested by striking some part of the breech of the gun. Just before this takes place the inclined face f of the extractor will strike the rim 9 of the cartridgecase, rocking the claw of the extractor slightly rearward about the point 6 This will cause the stop f on the shank f to swing out of engagement with the notch 6 and the wedging effect of the rim of the cartridge-case on the face f of the extractor will wedge the extractor upward until it assumes the position shown in Fig. 2. This upward motion of the extractor will compress the spring H. As soon as the claw of the extractor has passed clear of the rim of the cartridge-case the spring H will snap the extractor downward again until the inclined face f strikes the inclined face 70 of the gun, at which time the claw of the extractorwill be in front of the rim of the cartridge-rim. During part of or all of the brief interval required to move the extractor up and down, as just indicated, the breech-block is going through the process of being automatically locked, which is accomplished by turning the breech-block through ninety degrees, or to the position indicated in Fig. 8. This rotation of the breech-block causes the lever-arm f of the extractor to ride down the cam-groove b rocking the extractor forward and causing the lug f to engage under the notch 6 forcing the parts to assume the position shown in Fig. 3. During the angular movement of unlocking the breech-block or turning it to the position shown in dotted lines in Fig. 5 the springs H hold the extractors in the position shown in Fig. 3, and as soon as the breech-block starts rearward, under the action of the motor-piston, the claws f will bring up against the rim 9 of'the cartridge-case, tending to rock the extractors forward about the point a but this rocking motion is limited by the shank f and the notch 6 Owing to the inclination of the grooves in which the shank f is mounted, a straight pull backward on the claw of the extractor will tend to' wedge the extractor inward toward the axis of the bore, causing these claws to bite harder into the cartridge-case, so that the greater the strain the more firmly are the extractors held. After the cartridge-case has been dislodged from its seat there will be very little strain on the extractors, and the cartridge-case will be held with sufl icient rigidity under the action of the springs H, which will tend to keep the claws in engagement until the cartridge-case reaches the path of the ejector, (not shown,) by means of which it is knocked out of engagement with the extractors and is ejected at right angles to the axis of the breech-block, as fully described in the Benet and Merci patent aforesaid. The ejector mechanism, not being part of our present invention, will not be described herein.

It will be obvious that various modifications may be made in the herein-described apparatus which could be used withoutdepartiug from the spirit of the invention.
